From most preferred... CrDroid, EvolutionX, LineageOS, Bliss ROM.

I have had several Redmi phones. Yes, the current unlock process is a convoluted - You need a Xiaomi account. Then you need to toggle "unlock" in Developer settings. Then go to fastboot. Then while connected to your PC, you need the Xiaomi Unlock app to unlock the phone which you need to wait 2 weeks to happen. After 2 weeks, you go back to fastboot and the Xiaomi app, click Unlock and it is done.

(phew!)

It is tedious but not horrible. Once this is done, your bootloader is unlocked. You can then install your own custom recovery, custom rom, etc.

Redmi phones that have Qualcomm processors. Check out XDA forum for which models are supported.

Settings -> Sound and Vibration

You should see Phone ringtone - SIM 1 and Phone ringtone - SIM 2.

You must have the SIMs in your phone to see this.

FreeSpace 1 and 2!

I liked both Interstellar and Inception. I hated Tenet - on how the story was told and the inaudible sound (eye roll).

I remembered Crystal Skull as being not good. Then I watched Dial Destiny... Now Crystal Skull doesn't seem so bad in retrospect.

You can use bitwarden for passwords.

Sync what you can based on your threat model.

I backup what I can into a folder and then sync that to my backup drive. There are no way to backup app preferences without root.

You may need to log out of the old account on your phone and from the Mi Unlock software.

Install Hypatia on fdroid and do a scan of your phone.

13t pro probably. Check out the camera comparison vids.

Check out Simplewall. Simple enough and not complicated.
